How it Works
Magnetic particle inspection (MPI) is a non-destructive testing (NDT) method used to detect surface and slightly subsurface cracks in ferromagnetic materials such as iron, steel, and nickel. The process involves magnetizing the part to be inspected and then applying appropriate magnetic particles in the form of a dry powder or suspension to the surface of the part. The magnetic particles are attracted to areas of flux leakage, which are areas where the magnetic field is distorted by the presence of a crack or other defect creating a visible indication that can be used to identify and evaluate the nature and extent of the defect.
The application of the magnetic powder creates a visible indication of the location and shape of the crack or other defect. The powder accumulates at the location of the defect, forming a visible indication or "magnetic particle indication." This indication is then examined by a trained inspector using ultraviolet light or other illumination to identify the precise location, size, and orientation of the defect.
Technology
MR® Chemie uses its proprietary encapsulation technology for all the Magnetic Powders manufactured in its range making us one of the most advanced Magnetic Particle manufacturers in the world. Through extensive research and development, we have created a product that stands out from the competition, providing unparalleled sensitivity and performance. The advantages of our technology includes:
- Protection of the core material – Encapsulation provides a protective barrier around the core material, which can help to prevent degradation or loss of magnetic activity due to exposure from carrier media – oil or water and other additives. This can extend the shelf life of the product and improve its effectiveness.
- Improved stability: Encapsulation can improve the stability of the coating material by eliminating free unbonded pigment, thereby reducing the background and enhacing the stability.
- Versatility: Our Encapsulation technology is versatile and can be used with a wide range of core materials and encapsulating materials which helps us develop various products and compatible with aqueous based, hydrocarbon based and aerosols.
- Particle Size: Our controlled spray encapsulation method and miling allows us to precisely engineer particle size and offer batch consisitency from as low as 0.2 to 75 µm.
- Particle Shape – The core material is carefully milled to a unique physical morphology of the particle that offers high mobility, attraction and retention.
Through our advanced encapsulation technology, we are proud to offer the best product, providing unparalleled effectiveness and satisfaction to our customers.
